| Abstract: | Depolymerization of polyethylene terephthalate(PET) in sub-and supercritical water was carried out in a batch autoclave.The influences of experimental parameters,such as reaction time,reaction temperature and the ratio of water to PET,on the depolymerization ratio and the yield of TPA(terephthalic acid) and EG(ethylene glycol) were investigated.The HPLC,FT-IR,GC and GC-MS were used to analyze the solid product(TPA) and liquid product(EG),respectively.It was found that the depolymerization temperature and ti... |
